Question

An electric motor takes 5 A from a 220 V line determine the power of the motor and energy consumed in 2 h.

Answer 1

Step-by-step explanation:

Power = V^2/ R

R =V/I

so R = 220/5

R = 44 ohm

Power = 220×220/44

power = 1100 watt

energy = 1100/1000×2

=2.2 kwh

hope it will help u

Answer 2

$\huge \bf{Solution.}$

Given, I = 5 A, V = 220 V, t = 2h

Therefore, Power of motor,

P = VI = 220×5 = 1100 W = 1.1 kW

Therefore, Energy consumed = P t = 1.1×2

= 2.2 kWh

Thus, the power of the motor is 1.1 kW and energy consumed is 2.2 kWh.
